Will my AMD CPU work well with my nvidia graphic card?

Hi, Will my AMD CPU work well with my nvidia graphic card?
I also have two more questions:

1. Will the nvidia GPU fit on my motherboard? (specs will be down below)
2. Will the nvidia GPU work well with my AMD cpu?

My Specs right now:
AMD FX 6350 3.9GHz, 8GB RAM, HDD 1TB, AMD R9 280X 3GB, ASRock 990FX Extreme 3

New Graphic Card I want:

nVidia GTX 660 2GB

Your nVidia card will work just dandy with your AMD CPU ...

If you want 40% less frames than your R9 280X

The only reason why I'm getting a GTX 660 is because the game that I mostly play doesn't support AMD's, and I get constant FPS drops. I just wanted to know if it will be good together.

What is "the game you mostly play" where a GTX660 will beat an R9 280X ??

You might laugh, but San Andreas Multiplayer. AMD simply gives lag drops.
